Description

Technical Field

When the door is opened, the synchronous motor, the first motor and the second motor rotate the electric push rod, the load-bearing arm and the pedal to a suitable angle, and the electric push rod pushes the pedal out. When the passenger steps on the pedal, the synchronous motor, the first motor and the second motor rotate the electric push rod, the load-bearing arm and the pedal to a height level with the seat, which makes it convenient for elderly passengers to get on the car and improves the user experience of the elderly.

[0004] The retractable electric pedal for automobile disclosed in the above document has the following defects: the pedal and the load-bearing arm in this technical solution are connected through a third rotating shaft. Every time the pedal is stepped on, the connection between the pedal and the load-bearing arm will be subjected to greater pressure. During long-term use, the connection between the pedal and the load-bearing arm may be damaged, resulting in poor use effect.

[0005] It can be seen from this that the existing telescopic automobile electric pedal does not have an auxiliary support structure, and it is necessary to improve the existing shortcomings and provide a telescopic mechanism for an automobile electric pedal. Utility Model Content

The lower surfaces of the two first sliders 504 are hinged with support rods 505. The other ends of the two support rods 505 are hinged with a bottom plate 506.

[0030] When the pedal 7 is in use, the driving motor 503 is started so that the output end of the driving motor 503 drives the bidirectional screw 502 to rotate clockwise, so that the two first sliders 504 on the bidirectional screw 502 move axially toward one end thereof, and at the same time, the support rod 505 pushes the bottom plate 506 to move downward, so that the bottom plate 506 contacts the ground, thereby supporting the second connecting plate 501 and the pedal 7. After use, the driving motor 503 is started so that the output end of the driving motor 503 drives the bidirectional screw 502 to rotate counterclockwise, so that the first slider 504 drives the bottom plate 506 to reset through the support rod 505;

[0031] The connecting assembly 6 includes a first connecting block 601, which is arranged at one end of the second connecting plate 501, and a second connecting block 602 is arranged at the other end of the second connecting plate 501.

Since the outer surface of the limit block 604 is provided with an inclined surface, this will cause the second mounting plate 701 to push the limit block 604 to gradually slide into the cavity 603 when it moves downward. At the same time, the connecting rod 606 moves in the through opening provided on the lower surface of the first connecting block 601, and the spring 605 gradually contracts. When the pedal 7 is in contact with the second connecting plate 501, the mounting hole provided on the second mounting plate 701 is located on one side of the cavity 603.
